Hi, Simple change of values in vc4_kms.c to 4096x4096 is not sufficient to make it work. It allows me to create a new custom resolution using `xrandr`, but it fails...

After increasing pixel clock limit, I can apply that modeline, but it crashes driver and X server with following output in dmesg: ``` [ 33.581666] ------------[ cut here ]------------ [...
